Am converting the FHSQL Deski Reports(3.1) to Webi Reports(4.1).For the Below Query i have designed the universe,i.e i have created the derived table for the from clause select statement(which i have made bold in the query) and stored it as x.then i have created the predefined filter in universe for no exists functions(which i have made italics in the query).but while creating the report in webi if drag this filter am getting"no data to retrieve", i have validated SQL, Query Script is Correct.i don't have any idea how to proceed this query ..Suggestion Plss?....
